So I just checked my new one since I thought it was good for 10 years. No... only 5 now. My new US one is still good for 10, and without the new chip the US is requireing for other countries. On the plus side I will not have to get extra pages in the NZ one since it is 48 pages and between US and NZ I never get any stamps since I use my NZ one entering NZ and my US one entering the US.
